BEFORE STARTING THE
ENGINE
Before you operate your pressure washer, you should
prepare the engine for the initial starting. To operate
the engine you will need to do the following:
Add Engine Oil
IMPORTANT: Any attempt to crank or start the
engine before it has been properly serviced with the
recommended oil may result in an engine failure.
Note: When adding oil to the engine
crankcase, use only high quality detergent oil
rated with API service classification SF,SG, SH
or SH/CD rated SAE 30 weight. Select the oils
viscosity grade according to your expected
operating temperature. Do Not Use SAE 10W40
Oil.
Although multi-viscosity oils (5W30, 10W30, etc.)
improve starting in cold weather, these multi-viscosity
oils will result in increased oil consumption when used
above 32°F. Check your engine oil level more fre-
quently to avoid possible damage from running low on
oil.
Place pressure washer on a level surface.
Clean area around oil fill and remove oil dipstick
(Figure 8)
Wipe dipstick clean. Pour oil into oil fill opening until
oil reaches FULL mark on the dipstick. Stop occa-
sionally to check oil level. DO NOT OVERFILL.
Install oil dipstick, hand tighten securely.
Note: Check Oil Often During Engine Breakin.
Add Gasoline
DANGER! Never fill fuel tank indoors.
Never fill fuel tank when engine is run-
ning or hot. Do not smoke when filling
fuel tank.
WARNING! Never fill fuel tank completely
full. Fill tank to about 1/2" below the
bottom of the filler neck to provide space
for fuel expansion. Wipe away any fuel
spillage from engine and equipment before
starting.
The manufacturer recommends fresh, clean unleaded
regular automotive gasoline.
Use clean fuel and store in approved, clean covered
containers. Use clean fill funnels. Never use stale
gasoline left over from last season or gasoline stored
for long periods.
Clean area around fuel fill cap, remove cap
(Figure 9).
Figure 7 — Connect nozzle extension to spray
gun.
Figure 8 — Add oil to engine crankcase. Do not
attempt to start engine without
adding oil.

CHECKLIST BEFORE
STARTING ENGINE
If you have reached this point, look back over the
assembly to see if you have performed all of the fol-
lowing.
Check for properly tightened hose connections
(high pressure and water supply) and for tight con-
nections and that there are no kinks, cuts, or
damage to the high pressure hose.
Check that oil has been added to proper level in
engine crankcase before trying to start the pressure
washer.

HOW TO USE YOUR
PRESSURE WASHER
If you have any problems operating your pressure
washer, please call the pressure washer helpline at
1-800-270-1408.
You have assembled your high pressure washer and
have prepared the engine for starting. You are now
ready to clean your car, boat or the outside of a build-
ing or whatever you plan to clean.
How to Start Your Engine
The best way to start your engine-powered pressure
washer for the first time is to follow these instructions
step-by-step. This starting information also applies
whenever you start the engine after you have let the
pressure washer sit idle for at least a day.
Place the pressure washer in an area close enough
to an outside water source that can flow at a rate of
2 gallons per minute. Connect a garden hose to the
water spout.
Check that the high pressure hose is tightly con-
nected to the spray gun and to the pump. See
ASSEMBLY section for illustrations.
Connect the garden hose to water inlet on the pres-
sure washer pump and turn on the water.
Set Control Lever to RUN position.
Push primer bulb three (3) timeswait two (2) sec-
onds between each push. In cold weather
(55
0
F/13
0
C or below) push five (5) times.
Note: Do not use primer to restart a warm engine
after a short shut down.
Squeeze the trigger on the spray gun to relieve the
air pressure caused by turning ON the water.
Water will spew out the gun in a thin stream. This
will make it easier to pull start the engine. Release
the trigger.
Apply the safety latch to the spray gun trigger
(Figure 10).
Grasp rope handle and pull slowly until you feel
some resistance. Then pull cord rapidly to over-
come compression, prevent kickback and start the
engine. Let rope return to starter slowly.
How to Stop Your Pressure
Washer
IMPORTANT: Do not run pump without the water
supply connected and turned on. You must follow this
caution or the pump will be damaged.
First, move the control lever to STOP position.
Simply shutting OFF the engine will not release
pressure in the system. Squeeze trigger on the
spray gun to relieve pressure in the hose.
Note: A small amount of water will squirt out when
you release the pressure.
Figure 10 — Squeeze trigger to relieve water
pressure, release trigger and turn
the safety latch ON.

How to Use the Adjustable
Nozzle
You now should know how to START your pressure
washer and how to STOP it. The information in this
section will tell you how to adjust the spray pattern
and apply detergent or any other cleaning chemicals.
DANGER! Never adjust spray pattern
when spraying. Never put hands in front
of nozzle to adjust spray pattern.
On the end of your spray gun is a nozzle that you can
slide forward and backward and that you can also
twist from side to side. With the adjustable nozzle you
can adjust the spray pattern to be either high pres-
sure or low pressure. You can also adjust the spray
so it is concentrated in a stream pattern or expanded
into a fan pattern.
Slide the nozzle forward when you wish to adjust
the spray to low pressure mode (Figure 11). Slide
the nozzle backward to achieve high pressure.
Point the nozzle toward the ground and press the
trigger to test the pattern (Figure 12).
Twisting the nozzle adjusts the spray pattern from a
narrow pattern to a fan pattern.
For most effective cleaning, keep spray nozzle
between 8 to 24 inches away from cleaning sur-
face.
If you get spray nozzle too close, especially using
high pressure mode, you may damage the cleaning
surface.
Do not get closer than 6 inches when cleaning
automobile tires.

Applying Detergent with the
Adjustable Nozzle
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
IMPORTANT: You must attach all hoses before you
start the engine. Starting the engine without all the
hoses connected and without the water turned ON
will damage the pump.
To apply detergent follow these steps:
Review the use of adjustable nozzles on Page 10.
Prepare the detergent solution as required by the
job.
Hang the detergent solution on hook of the wire-
form on the handle as shown in Figure 13.
Place small filter of the clear, detergent siphoning
tube into the detergent container.
Slide the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with nozzle in
high pressure position.
IMPORTANT: Detergent cannot be applied without
the water source turned on.
Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to
spray gun and pump (see ASSEMBLY), and start
engine..
Apply detergent to a dry surface, starting from the
bottom and working up.
Allow the detergent to soak in between 3-5 minutes
before washing and rinsing.
For washing, start at lower portion of area to be
washed and work upward, using long, even over-
lapping strokes.
CAUTION: Keep the plastic injector tube
from coming in contact with the hot muf-
fler. This will damage the plastic tube.
When inserting the filter into a cleaning
agent bottle, route the tube so as to keep it
from inadvertently contacting the hot muf-
fler.
Pressure Washer Rinsing
WARNING: Be extremely careful if you
must use the pressure washer from a
ladder, scaffolding or any other relatively
unstable location. Pressure in a running
washer builds as you climb. When you
press the trigger, the recoil from the initial
spray could force you to fall. The high pres-
sure spray could also force you to fall if you
are too close to the cleaning surface.
For Rinsing:
Slide nozzle forward to high pressure and wait for
detergent to clear.
Keep the spray gun a safe distance from the area
you plan to spray.
Apply a high pressure spray to an small area and
then check the surface for damage. If no damage
is found, you can assume it is okay to continue
cleaning.
Start at top of area to be rinsed, working down with
same overlapping strokes as you used for cleaning.
Note: You can also stop detergent from flowing by
simply removing siphon from bottle.

GENERAL MAINTENANCE
RECOMMENDATIONS
The warranty of the high pressure washer does not
cover items that have been subjected to operator
abuse or negligence. To receive full value from the
warranty, operator must maintain high pressure
washer as instructed in this manual.
Some adjustments will need to be made periodi-
cally to properly maintain your high pressure
washer.
All adjustments in the Service and Adjustments
section of this manual should be made at least
once each season.
Once a year you should clean or replace the spark
plug and clean or replace the air filter and check the
gun and wand assembly for wear. A new spark plug
and clean air filter assure proper fuel-air mixture
and help your engine run better and last longer.
BEFORE EACH USE
Check engine oil level.
Check water inlet screen for damage.
Check high pressure hose for leaks.
Check detergent inlet hose and filter for damage.
Check gun and wand assembly for leaks.
PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine screen on the water inlet. Clean if the
screen is clogged or replace if screen is damaged.
Check High Pressure Hose
High pressure hose can develop leaks from wear,
kinking, or abuse. Inspect hose each time before
using it. Check for cuts, leaks, abrasions or bulging of
cover, or damage or movement of couplings. If any of
these conditions exist, replace hose immediately.
DANGER: Water spraying from a leak is
capable of injecting material into skin.
Inspect hose each time before using it.
Never repair a high pressure hose.
Replace it with another hose that meets
minimum pressure rating of your pres-
sure washer.
Check Detergent Hose
Examine the filter on the detergent hose and clean if
clogged. Hose should fit tightly on barbed fitting.
Examine hose for leaks or tears. Replace the filter or
hose if either is damaged.
Check Gun and Wand
Examine hose connection to gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Put safety
latch in ON position and test trigger. You should not be
able to press trigger.
Purge Pump of Air and
Contaminants
To remove the air from the pump, follow these steps:
Set up the pressure washer as described in the
ASSEMBLY section and connect the water supply.
Remove the wand extension from the gun.
Pull the trigger on the gun and hold.
To remove the contaminants from the pump, follow
these steps:
Set up the pressure washer as described in the
ASSEMBLY section, and connect the water supply.
Remove the nozzle attachment from the gun.
Start the engine according to instructions in OPER-
ATION section.
Squeeze the trigger on the gun and hold.
When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
attachment.
Cleaning Chemical Injector Hose.
If you have used the chemical injector hose you must
flush it with clean water before stopping the engine.
1.Flush for five minutes.
2.Shut off the pump.
3.Simply shutting OFF engine will not release pressure
in the system. When engine has shut down,
squeeze the trigger on the gun to relieve the pres-
sure in the hose.
Nozzle Maintenance
If the adjustable nozzle becomes restricted or
clogged with foreign materials, such as dirt, excessive
pump pressure may develop. If this nozzle becomes
partially clogged, it can cause a pulsing sensation
during use. This generally is not a pump related
problem, but rather a clogged or partially restricted
adjustable nozzle.
If the adjustable nozzle becomes clogged or partially
restricted, immediately clean the nozzle with the kit
included with your pressure washer by following
these instructions:
Shut off the engine and turn off the water supply.
Separate the wand extension from the gun.
Adjust the wand extension to the stream position.
Remove nozzle from the end of the wand extension
(Figure 17) using a 2mm or 5/64 allen wrench (like
the one included in the kit).
Use the wire included in the kit (Figure 17) or a
small paper clip to free the foreign materials clog-
ging or restricting the nozzle.
Figure 17 — Removing and cleaning nozzle.
Remove additional debris by back flushing water
supply through wand extension (Figure 18). Back
flush between 30 to 60 seconds. Turn wand exten-
sion to stream spray and move nozzle from low to
high while flushing.
Figure 18 — Backflushing the nozzle.
Reinstall nozzle into the wand extension. DO NOT
over tighten.
Reconnect the wand extension to the gun.
Reconnect the water supply, turn on the water, and
start the engine.
Test the pressure washer by operating with nozzle
in the high and in the low position.
